Learn Class 9 Math - Triangles

The figure that is enclosed from three sides is known as a triangle. Many properties are present that help show the congruence of triangles, like SAS, SSS, ASA, AAS, and many other terms.

A different set of criteria for the Congruence of the triangle

1. SAS:

• The SAS property makes the triangle congruent by its two sides and one angle.
• It means when in a given triangle, the two sides are equal, and one angle is equal, the triangle becomes congruent by the property of the SAS rule.

2. AAS:

• The AAS property makes the triangle congruent by its two angles and one side.
• It means when in a given triangle, the two angles are equal and one side is equal, the triangle becomes congruent by the property of the AAS rule.

3. SSS:

• The SSS property makes the triangle congruent by its three sides.
• When in a given triangle, all the three sides are equal. The triangle becomes congruent by the property of the SSS rule.

4. ASA:

• The ASA property makes the triangle congruent by its two angles and one side.
• It means when in a given triangle, the two angles are equal and one side is equal, the triangle becomes congruent by the property of the ASA rule.
